Probably the best race you don't know about (yet)

Most "small" events that only operate in one or two states and host 3 or 4 events in a given year are usually somewhat below par - that is clearly not the case with Terrain Mud Run. From the quality and number of obstacles on a 5k to 12 mile course to the friendliness and professionalism of the staff, you'd be surprised that you weren't at one of the "big" name OCR's with ample resources. I interviewed the owner, Jerry Foreman, and we got into a long discussion about obstacle spacing, specific groupings and what it takes to build a fun, challenging, and well-paced course - this guy clearly gets it and it shows in the enjoyment of everyone who challenged all of the different distances of the Terrain Phoenix course. I chose the 12+ miler, and while it was 2 somewhat tough laps around the course which offered a dozen or so obstacles, it surely wasn't boring. Actually, Terrain Mud Run jumped up my list of mud Runs & OCR's to the top 3!
With no "theme" like zombies or warriors to make Terrain extremely memorable, they may not have the buzz of many large races have - but while I was speaking with other racers, I came across several repeat offenders who look forward to the Terrain events in Tucson, Phoenix, Flagstaff and Las Vegas... I know in 2014 I will!
